Crossostylis multiflora Brongniart & Gris (1861a: 378) .

Haplopetalon multiflorum (Brongn. & Gris) Baillon (1862: 40) as ‘Haplopetalum multiflorum’. Lectotype (designated here):— NEW CALEDONIA, Balade, 1855–1860, Vieillard 43 (P00402853!) .

The name Crossostylis multiflora was validly published by Brongniart & Gris (1861a) in a footnote added in press with the citation of a specimen, Vieillard 43, and a comparison with C. biflora and C. grandiflora, which can be considered as a diagnosis. It was therefore already a valid name when Sebert & Pancher (1874) published a description of the species. Only one sheet of this number at P appears to bear Brongniart’s original handwriting and it is treated here as the lectotype (P00402853!). Another sheet of Vieillard 43 (P05574280!), has a different locality (Wagap) and cannot be considered as an isolectotype.
